This negates the requirement for coke ovens and sinter plants which reduces capital and operating expense. The main objective of the HRDF was to demonstrate the process and engineering scale up of the core plant and to provide operating data for commercial evaluation. Etchnology, indication of copyright fee is not available.

Construction of the HRDF with a design capacity oftons per annum, commenced in The partnership seeks to finalize the development of HIsmelt technology and to work together to further improve the technology to higher levels of tschnology and economic performance. Services for libraries National interlibrary loan International interlibrary loan.

The plant had achieved a production rate of 80 tons of hot metal per hour in early with a coal rate of kg per ton of hot metal.


HIsmelt process of Ironmaking

HIsmelt is short for high intensity smelting. Construction of the plant was started in January This combustion occurs in the relatively oxidizing region in the upper section of the SRV. But some iron making technologies like finex, HIsmelt and HIsarna are technologically sound and have potential to have better techno-economics. This is done through large amounts of liquid splash moving between the two regions.

The core of the HIsmelt process is the smelt reduction vessel SRV which has a refractory lined hearth and water cooled upper shell.

The vertical vessel demonstrated major improvements in terms of refractory wear, reliability, availability, productivity and simplicity in design.

Reaction gas CO and coal devolatilization products which are generated from deep within the bath form a fountain of mostly slag and some metal.

The heat transfer between the upper oxidizing regions to the lower reducing region is achieved in such a way that the oxygen potential gradient is hisnelt. Slag is formed by fluxing the gangue in the iron ore and ash in the coal with lime and dolomite.

Further there is big reduction in dust emissions and specific wate consuption. Cold commissioning commenced in the second half of while the hot commissioning was carried out in second quarter hizmelt Course reserves Setting up a course reserve Form for setting up a course reserve.


This stage of operation confirmed uismelt the process was ready to be scaled up to level of a commercial plant. High phosphorus iron ore fines have no adverse effect on the phosphorus reporting to the hot metal. Byproducts of the process are slag and off gas. Slag can be granulated or technoloy into pits for further processing. This operating flexibility maximizes productivity, as it is easy to maintain a steady state operating window.

Posted by Satyendra on Jul 2, in Technical 2 comments. Since the slag is batch tapped through a slag notch, the hot metal is slag free. Trials were conducted in a 60 tons OBM converter to demonstrate the fundamentals of the smelt reduction process.

The HIsmelt process smelts iron ore and coal in a water cooled refractory lined vertical vessel to produce hot metal suitable as feed to BOF’s and EAF’s.
